Patent CA-2387374-A1 (CA)
Inventor: SMITH MARK D
IPC: G01S13/933
Filed: 2000-10-12
Abstract: A system for determining a bearing to a radio signal source includes four antennas and a computer. The computer accepts signals from the antennas as inputs and identifies which antenna is providing the largest amplitude signal and which antenna is providing the next-largest amplitude signal. These amplitudes are subtracted to determine an amplitude difference. The bearing is then determined in accordance with a linear function of the amplitude difference. The linear function is a model of the piece-wise linear approximation of antenna signal amplitudes accepted by the computer. The slope used in the linear function depends on the identity of the antenna that provides the largest amplitude signal. When the antenna that provides the largest amplitude signal is mounted on a fuselage oriented toward a curvature of the fuselage, as when facing port or starboard, then a different slope is used than when the antenna that provides the largest amplitude signal is mounted on the fuselage and oriented toward for or aft. More accurate bearing calculations result from use of different slopes accounting for fuselage shape and elevation angle resulting from a difference between the altitude of the system and the altitude of the radio signal source. Bearing may be used for aircraft traffic alert and collision avoidance systems.

IPC: B23K35/26
Filed: 2002-06-10
Abstract: A Pb-free solder alloy is designed from the Sn based substrate, which is a non-toxic and environmental friendly metal. The Pb-free solder includes a binary composition consisting essentially of about 96.5 weight % Sn and 3.5 weight % Ag, having an eutectic temperature of 221 degree Celsius. In addition, a Pb-free solder includes a ternary composition consisting essentially of about 95.5 to 96.5 weight % Sn, 3.0 to 3.5 weight % Ag, and 0.5 to 0.7 weight % Cu, having off eutectic melting temperatures of about 215-220 degree Celsius. The said solder compositions can be modified with addition of 0.1 to 1.0 weight % P, to enhance better micro-structural stability and to reduce dross formation, during Hand Soldering, Wave Soldering, and Reflow Soldering in Electronics Assembly Processes.

Filed: 2001-06-12
Abstract: L'invention concerne un relais de protection électronique (1) qui émule un relais de protection électromécanique de sorte que la protection assurée par les deux types de relais puisse être coordonnée dans un réseau de distribution d'énergie électrique. Ce relais de protection électronique (1) comprend un processeur numérique (15) qui incrémente une valeur de comptage de retard variable au moyen d'une fonction de courant inverse et une valeur de comptage de retard fixe au moyen d'une valeur proportionnelle correspondante. A chaque exécution de la routine, seule la valeur de comptage la plus faible est augmentée de sorte que les deux valeurs de comptage sont forcées de se suivre. Lorsque les deux valeurs de comptage atteignent une valeur de déclenchement, un signal de déclenchement est généré. Le processeur (15) applique également une fonction de réinitialisation lorsque le courant mesuré est inférieur à une valeur d'excitation. Selon la caractéristique de réinitialisation préférée, la valeur de comptage de retard variable est réduite au moyen d'une fonction de courant inverse et le retard fixe est réduit de la même valeur.
Patent CA-2412852-A1 (CA)
Inventor: POTTER SIMON
IPC: C12Q1/6895
Filed: 2001-06-21
Abstract: The present invention relates to a novel method for the prediction of fibre length and the rapid selection of superior trees for given pulp and paper product lines using a DNA probe. The method comprises the isolation of tree genomic DNA from a hybrid spruce live tissue source, hybridization of the spruce DNA probe to that genomic DNA and the densitometric assessment of the intensity of the hybridization pattern obtained. This determines the precise degree of genetic admixing (or introgression) of the two parent species within the hybrid population. Due to the linear relationship - in the hybrid spruce population examined - between degree of genetic introgression and fibre length (discovered in this method), the intensity of the DNA probe hybridization pattern can be used to directly, accurately and reproducibly predict the fibre length found (for a given tree age) within an individual hybrid spruce within the population.

Abstract: The invention includes an interactive Internet, television or media scrambler and decoding mechanism. A fixed or variable encrypted image is printed onto a clear or translucent film and is placed in front of a broadcasted descrambler to decode the hidden image. An oscillating, zooming image is projected on the monitor or television screen, which aligns in proper phase with the scrambled image, thereby disclosing the hidden image. The scrambled image and descrambler can also be reversed to maintain control of the hidden image at the website or television transmission site. Conventional inks may be used with sufficient scuff resistance to create the printed image, or a primer may be applied for added protection. The oscillating, zooming image provides a means for uniformity between equipment, processors, software and browsers.
